A storage administrator is tasked with creating a DR solution for block and file storage resources. The company has multiple regional and international sites containing a mix of Dell EMC Unity XT and Dell EMC UnityVSA systems.

What are considerations for the storage administrator in creating the DR solution?

  1. Synchronous remote replication should be restricted to within 100 miles between sites to keep latency below 10 ms
    Block storage resources can be replicated synchronously and asynchronously
  2. Asynchronous replication ensures zero data loss the remote replica in disaster conditions
    Block storage resources can be replicated synchronously and asynchronously
  3. Asynchronous replication over long-distance does not impact latency
    Asynchronous replication ensures zero data loss to the remote replica in disaster conditions
  4. Synchronous remote replication should be restricted to within 100 miles between sites to keep latency below 10 ms
    File and block storage resources can be replicated synchronously and asynchronously

Answer(s): C
